General rules
Might (Might Hero)
Wisdom. If a Might Hero is offered Wisdom at level i, the next level will be offered no later than level (i + 6).
Magic School. If a Might Hero is offered any Magic School at level i, the next level (Basic, Advanced, Expert of one of the four Magic Schools) will be offered no later than level (i + 4).
Magic (Magic Hero)
Wisdom. If a Magic Hero is offered Wisdom at level i, the next level will be offered no later than level (i + 3).
Magic School. If a Magic Hero is offered any Magic School at level i, the next level (Basic, Advanced, Expert of one of the four Magic Schools) will also be offered no later than level (i + 3).
A skill offered forcibly will always be in the left slot. With the exception of the case when Wisdom and a Magic School must be offered forcibly. Then Wisdom has priority over the Magic School.
So, there is a bug (it is precisely a bug) due to which Elementals receive forced levels of Wisdom and Magic Schools not as Magic Heroes, but as Might Heroes. This means, for example, that after receiving Advanced Wisdom at level 4, you will have to wait until level 10, in the worst case, for Expert Wisdom, and not until level 7!
LM Oracle 3.75
2VDV_forever: This means that this number is stored in the memory cell until purchase. There is nothing you can do about it.
2Kamikaze: Are all the parameters set correctly? By the way, the cursor has nothing to do with it. You don't need to hover over it at all. The damage calculation depends only on the parameters you entered.
